Canada's cannabis legalization and drivers' traffic-injury presentations to emergency departments in Ontario and Alberta, 2015-2019.

Background: Worldwide momentum toward legalization of recreational cannabis use has raised a common concern that such policies might increase cannabis-impaired driving and consequent traffic-related harms, especially among youth. The current study evaluated this issue in Canada.

Methods: Utilizing provincial emergency department (ED) records (April 1, 2015-December 31, 2019) from Alberta and Ontario, Canada, we employed Seasonal Autoregressive Integrated Moving Average (SARIMA) models to assess associations between Canada's cannabis legalization (via the Cannabis Act implemented on October 17, 2018) and weekly provincial counts of ICD-10-CA-defined traffic-injury ED presentations.

Providing and funding breast health services in urban nurse-managed health centers.

Nurse-managed health centers (NMHCs) are an innovative health care delivery model that serves as an important point of health care access for populations at risk for disparities in health outcomes. This article describes the process and outcomes of clinical breast health services in two NMHCs located in a large Midwestern city. Findings indicate that client's knowledge about breast health was increased after they received breast health services from NMHC nurses.

Multicompartment model of lung dynamics.

A mathematical model was developed to simulate the function of the lungs. The lungs are represented by 24 compartments each corresponding to a generation of the Weibel model A. In the model it is assumed that gases are transported in the lungs by convection and diffusion from one compartment to the other.
